GRS and Medieval Studies have contacted us independently with similar requests for a map and database installation to allow people to click on the map and see who or what happened when at that site, or to search for a person and see where they were when. I've already done a rough spec for Medieval and will get them to confirm that and then we can compare that to what GRS wants and after a couple of iterations we should be able to come up with a solution that encompasses both of them.
